What’s on the Kirchhoff's Laws poster
The rule, 3 worked examples, and the mistake everyone makes.
- Current into a junction equals current out. The sum of EMFs around a loop equals the…
- ΣI(in) = ΣI(out) · ΣE = ΣIR
- Junction with 3 A in = 3 A total out
- Loop with 12 V EMF = Drops sum to 12 V
- Sign convention = Consistent direction around the loop
- Common mistake: Mixing sign conventions between loops → Choosing one direction and ap…
For n unknowns you need n independent equations. Count loops and junctions before starting.

- Who is the Kirchhoff's Laws poster for?
- Kirchhoff's Laws belongs to the Physics section rather than to a school year, because physical science is not something one grade owns. Anyone learning electromagnetism can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Kirchhoff's Laws poster?
- Current law is conservation of charge. Voltage law is conservation of energy. A wall chart earns its place by being glanceable from where the work is happening, so Kirchhoff's Laws belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Kirchhoff's Laws?
- AC Circuits, Capacitance and Circuit Basics sit alongside Kirchhoff's Laws in the Physics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AC CircuitsCapacitanceCircuit Basics
- Is the Kirchhoff's Laws poster free to download and print?
- Yes. Kirchhoff's Laws downloads as a free PDF with no account, no email and no watermark, like everything else in the Physics section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Kirchhoff's Laws poster print at?
- Kirchhoff's Laws is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Kirchhoff's Laws loses nothing.Printing guide
